Sink or swim?

What can you tell a flatlander about living amongst landslides, sinkholes, and Karst topography?

I've long lived in very flat areas, but I recently moved to the metro east area of St. Louis in Illinois. My husband and I are looking for a house along the bluffs in that area that has a couple acres. We've now found a place we like, but we are both concerned because it is closely located to some sinkholes. They aren't on the property, but they next to the road that links us to the main road.
The property itself is mostly flat, but sloped. The area isn't close enough to a cliff or any major depression that I'm worried about landslides, but I am worried about future sinkholes. I've looked at this Sinkhole Plain Area Assessment from the Illinois DNR and from what I can tell the whole area is prone to this kind of activity.
What I'm wondering is if we will be more at risk because the area immediately east of us has sinkholes or if the risk is more or less constant. Of course, some of this might be land specific so my next question was is there anyone who does land inspections? I know this wouldn't fall under a home inspection, but I wasn't sure who to contact to find more about this particular property. The place looks nice but I'd hate for it to fall into a sink! If you think I'm completely too worried about this let me know because honestly, I'm used to ground that stays where it is supposed to.
